If meningioma grows on the top of the head, it may be mainly headache, dizziness, nausea and seizures; If it is at the bottom of the anterior cranial fossa, that is, behind the orbit, most of them will lose their vision and sense of smell; If it is in the posterior cranial fossa, that is, the position of the back of the head, it may be manifested as hearing loss, facial sensory impairment, and cerebellar balance function, but most patients often have headache and epilepsy as the first symptoms.
Whether meningioma can inherit the pathogenesis of meningioma is still unclear. The general view in the medical field is that meningioma is related to some internal and external stimuli, such as head trauma, intracranial infection, environmental pollution, ionizing radiation and chemical drug stimulation. The occurrence of meningioma may also be related to genetic factors, but so far, there is no reliable evidence to prove that meningioma is a genetic disease.
Is the scalp of meningioma protruding? Meningiomas originate from the proliferative tissue between meninges. Where there are arachnoid granules, it is possible to produce meningiomas, but arachnoid granules are often located in the cranial cavity, so generally speaking, meningiomas are invisible on the scalp. However, any situation is special. For malignant meningioma, besides intracranial erosion, it can also erode the skull and scalp, so patients with this kind of meningioma may feel obvious protrusions on their heads.
4 How to alleviate the increase of intracranial pressure in patients with meningioma is mainly due to the increase of tumor volume or edema of brain tissue around the tumor. The symptoms of intracranial hypertension are affected by the size, location, nature and growth rate of the tumor. After increased intracranial pressure, patients mainly showed symptoms such as headache, nausea, vomiting, papillae edema, and some patients also had disturbance of consciousness, vision, incontinence and so on. So meningioma is clinically. Surgery is the first choice for patients with increased intracranial pressure, and tumor lesions are removed. Some related drugs such as dehydration to reduce intracranial pressure, sedation and analgesia are generally effective.
